Homework Help: Polar area between two equations

  1. Oct 26, 2007 #1
    [SOLVED] Polar area between two equations

    1. The problem statement, all variables and given/known data

    Using polar coordinates, find the area of the region shared by both curves [2cos(theta) and 2sin(theta)]


    2. Relevant equations
    .5integral((2cos(theta) - 2sin(theta))^2)dtheta)


    3. The attempt at a solution

    Ok. So I know what equation I have to use. I also know that one of the limits of integration will be pi/4 (the point that's not on the origin). However, I don't know what theta value represents the point on the origin. I may be doing this all wrong. Any help is appreciated.
